1. Since the impeller of the blower operates in the body without friction, it does not need lubrication,
The blower keeps the exhaust gas free of oil. It is an ideal pneumatic conveying gas source for chemical, food and other industries.
2. The blower is a volume operated blower. When in use, the flow changes little with the change of pressure. But the flow changes with the speed. Therefore, the selection range of pressure is very wide, and the selection of flow can be achieved by selecting speed.
3. The speed of the blower is high, the gap between the rotor and the rotor, between the rotor and the body is small, so there is less leakage, and the volume efficiency is high.
4. The structure of the blower determines that its mechanical friction loss is very small. Because only bearing and gear pair have mechanical contact on material selection, rotor, casing and gear ring have enough mechanical strength. Safe operation and long service life is a major feature of blower products.
5. The rotors of the blowers are checked for static and dynamic balance. The finished product runs smoothly and has little vibration.
⒍ the blowers with the above characteristics are mainly roots blowers, side flow blowers and multi-stage centrifugal blowers.
